A 70-year-old man presenting with long standing grade 3 Haemorrhoids, underwent open haemorrhoidectomy under spinal anaesthesia. The patient passed stools on subsequent day and there was no bleeding per rectum. On day 5, he complained of dull aching upper abdominal pain. On physical examination, the abdomen was soft and there was mild tenderness in the epigastric region. Subsequently, he developed high temperature with chills and rigors. His condition failed to improve and the abdominal pain increased in severity. There was no pain in the perianal region and per rectum examination was normal. Leucocyte count rose to 12×109/L and there were toxic changes on peripheral smear. Blood culture grew Staphylococcus aureus. Liver enzymes were mildly elevated. Coagulation profile was deranged. Fibrin degradation products were positive. D-dimer was high. CT revealed acute thrombosis of left portal vein and microabscesses suggestive of portal pyaemia.
